BATTERY CONNECTION FOB MOTOR VEHICLES.

Application filed January 12, 1927. Serial No. 160,734.

My invention relates to improvements in Fig. 6 is a view of the cleats and bolt asbattery connection for motor vehicles. sembly.

The object of my invention is to provide a Like characters of reference designate like device of the character described, which will parts in all the figures.

be new, useful, novel and of utility; which I accomplish the results sought to be 60 will be easy to install and to remove; which brought about by my invention as follows: will be easily and cheaply manufactured, I provide a terminal body 1 composed of constructed and maintained; which will be lead of suitable weight according to the size simple, strong and durable; which will not of the battery; the top 2 thereof is in pracbe damaged by the acid and chemicalsof the tically the form 'of a Y having upper and 65 battery; which will eliminate the forming outwardly extending arms 3, 1, and cut-away of all corrosions, disintegrations, hard beveled portions 5, 6, on the inner surfaces of crustings, and the like that ordinarily form said upper arms, and a groove or slot 7 at around brass, or copper terminals at the posithe union of said portions cut down into 1 tive .posts; which will have very few parts the lower stem of said Y-shaped top. At 7 exposed to the effects or affected by the acids the right of said Y-shaped topportion is a and chemicals of the battery in any way, and cut-away portion 8, 9, 10, forming a secthese are so formed and constructed that ondary top portion 10, and on the side therethey can be easily removed and easily and below a similar cut-away portion 11, 13, 14,

cheaply replaced; which is so formed that forming a side wall12, the line between said 75 the flange at the top of the cleats and the top portion 10 and saidside wall 12 forming extra thickness of the metal at the top of a shoulder 1.5; said side wall 12 has a centhe terminal body forces the bottom of the tral perforation 16 therethrough below said cleats to bite on the battery post at the bottop portion 10 and at such a point as to be tom; which will preventthe necessity of above the terminal posts hereinafter referred 80 burning on the new terminals. c v to; a similar cut-away portion and a similar It is generally known to those familiar top portion, and a similar side wall to the with the art to which my invention pertains ones above described are on the left side of that the'contents of the commonly used batsaid Y-shaped top portion 2 as are partially 3 ing and corroding, causing a stiff or crusty said secondary side wall also has a central sediment over the outside surface of the batperforation in line with perforation 16 both tery, and that this injures the battery and its perforations adapted to receive a bolt 17, connections and requires the burning on of hereinafter referred to, therethrough; at the new terminals. All of this and other defects outer edge of said body 1 near itsbottom isv 90 of the present systems of connections are an outstanding lup; 22 having a lateral perrelievcd and remedied by the use of the foration 23 therethrough, adapted to receive present invention. one end of a battery wire 24, and to contact With the above and other objects in view one of the battery posts; the flat bottom 25 as will more fully appear from the specifiof said body 1 surrounds a central bore 26 9,5 cation, claims, and drawing, my invention therein and fits downflat upon the top face consists in the details of constructionand of the battery 4-9, and said bore 26 is combination of parts more fully hereinafter adapted to surround one of the terminal described. One construction embodying one posts of'said battery; the front of said body 45 form of my invention is shown in the achas two fiat surfaced front faces 27, 28, with companying one sheet drawing, of which, a space between them, the walls surrounding Figure 1 is a'perspective view of a battery said space having flat surfaces 29, 30, at right showing the terminal connections installed angles to said surfaces 27, 28; the lower outon one of the battery terminals, or posts; side surface 31 of said body 1 forms ashoul- Fig. 2 is a perspective view of the terminal der 32 between said surface 31. and said 105 connection assembled; Fig. 3 is a perspecledge 13. I tive view of a metallic flanged cleat covered I also provide two cleats made of iron, or with lead; Fig. 4C is a perspective view of the other suitable metal, coated with lead. These terminal body; Fig. 5 is a perspective View similarly formed and used, respectively,

teries is constantly seeping out or overflowshown at 17, 18, 19, 20 and at shoulder 21; r

of the under side of the terminal body; on each side of the said array 1, and 119 adapted to fit in the cut-away portions thereof. As will be best shown in Fig. 3, the cleat has a shoulder 37, and an inwardly extending and tapering flange top 38, its side edges 34C, 86, and its innermost edge fit the oppositely shaped edges 17, 19 and 18; the underside of top 33 fits snugly on said secondary top 20; its outer vertical edges (not numbered) fit, respectively, the cutaway beveled edges of said top 20 (not numbered) but similar to like portions shown at 11, l3, 14:, Each of said cleats has a central perforation adapted to be used in line with each other, one such perforation is shown at 41; these are also. adapted to fit zconjju'gately perforation l6, and a similar perforation in the opposite wall of said body (not shown) a bolt e7 with a head 46 and a nut 4 8, preferably coated with lead is adapted topass through said perforations in said cleats, and the perforationsin said side walls 12 and'lQ, and to hold said cleats securely "to the walls of said body snugly around the terminal post of a battery such ,is shown at 4:9. Said battery ist'he usual form of battery varying in size according to its demand ,and the make, having the usual handles 51, 52, acid caps 58,54, '55, with vent holes 56, 57, 58,

- connecting plates 59, 60, and terminal post Gland a second terminal post not shown in the drawing as it is coveredup by the applied battery connection. The flange 33 at l the top of said cleat, the extra thickness of the metal at the top of theterminal body, the thinner walls of the terminal body at its bottom, and the strength of the metallic cleats, bolt and nut, forces the bottom of the cleat as, shown at the bottom 39' to pressagainst the lowenbotto n walls of said body, and" causes the walls in turn tobite on the battery post surrounded by said walls.

' From the description of the accompanying one sheet, drawing, the specification and the claims, the I advantages of the construction,

application of the parts and the combina tions thereof, will be apparent to those familiar with the art to which my invention pertains.- I have entered into a detailed description of the construction and the rela tive,arrangement of the parts embraced in the present embodiment of invention in order to impart a full, clear and exactunderstanding of said embodiment. I do not desire, however, to be understood as confining myself to thespecific construction and relative arrangement of the partsinasmuch as in the future practice ofthe invention various changesand modifications may bemade such as fall within the scope of my invention without departing from the principle thereof. a a e Having thus described the invention, what is claimed and desired to be secured by Letters Patent, is:
